Strange error on Game Dev Tycoon


I was playing my game last night, and when I tried opening it this morning I got this error:

Error Alert
TypeError: Cannot read property ‘length’ of undefined

If the issue persists please report this error to

It can happen when the game is updating or when you manipulated something. To fix it, just reinstall the game!
